My husband and I bought a used Dimension One Californian Spa 2 years ago. We love it….but we are having recurring issues with it. We have to date had to replace the heater, both pumps, and have replaced the circuit board 4 times. The circuit board keeps burning up (with smoke and flames). We originally thought that maybe the problem was that we were running the pump cycles back to back and the board couldn’t handle the draw, thus resulting in overheating. That worked fine for the last 6 months…but it again is starting to smell of electrical overheating. The circuit board has not burned up again because we caught in time and turned the spa off. Does anyone have any advice as to what the problem can be?
